Chemical action where a solid disintegrates (dissociates) into a gas without going through a liquid state or phase. For instance, because the climate in Colorado is so dry snow does not always melt into liquid water but will sublimate directly into water vapor disappearing from the ground directly into the atmosphere. Another example is faded paint on a road sign is the paint sublimating (disintegrating) into the air by chemical action of heat, oxygen and ultraviolet light. Likewise water evaporating from the surface of the ocean is actually the complex or compound water molecules disintegrating into simple molecules and/or atoms of water.

Giuliano Kremmerz
“The state of the magician begins with the first sublimation of the earthly being, that is, the acquisition of a state of sensitivity, understood not in a passive religious sense, but in an active and volitional sense, in which the purification of all other material actions of a lower level is possible, thanks to sublimation both through method and through consciousness.
The human body is an alchemical athanor for those who have become familiar with the occult truth, like a pot in which the earthly aspirations by which an ordinary mortal lives are digested and boiled. In the human body, which contains analogues of everything that is present in nature in all its fourfoldness, there is an instrument for the highest purification of the four elements themselves, so that you can gradually achieve a higher state, which the Jews called the state of Yod, since the mysterious Tetragrammaton is contained in the world and is reflected and comprehended in any of its particles and especially visibly in man, who is fourfold in all the infinity of his manifestations.” [Giuliano Kremmerz "Corpus philosophorum totius magiae"]
